PRODUCTION METHOD OF SLAG, PRODUCTION SYSTEM OF SLAG AND SLAG

摘要

PROBLEM TO BE SOLVED: To prevent a water-granulated slag from adhering to conveying equipment and pulverizing equipment or damaging these equipment.;SOLUTION: In a water-granulating step, a molten slag obtained by a reduction furnace 40 is water-granulated at a water granulation water amount/a molten slag amount of 10-40 to generate a water-granulated slag having a fineness modulus of 5 mm or less. In a water content control step, water content adhered to the water-granulated slag is separated while conveying the water-granulated slag by a belt conveyer 60, and the water-granulated slag from which water content has been separated on the belt conveyer 60 is placed on a water-granulated slag depot 70, so that a water content of the water-granulated slag having a fineness modulus of 5 mm or less is controlled to 4% or less.;COPYRIGHT: (C)2015,JPO&INPIT
